If you don't like your sister or don't get along with your father, let's find out if you like yourself. Let's not sugarcoat anything about it.
If you like yourself, other people will like you
You have to be happy with who you are and the choices you make. If you don't like yourself, you'll never be truly happy.
You have to like yourself before you can do anything!
Don't ever write anything you don't like yourself and if you do like it, don't take anyone's advice about changing it. They just don't know.
The more you like yourself, the better you perform in everything that you do.
